A&N PWD Schedule of Rates
About Andaman Public Works Department
A&N's geography — 572 islands across 8,250 km² spanning ~750 km north-south, with only 38 inhabited — drives unique construction logistics. Materials reach Port Blair via sea from Chennai/Kolkata; onward distribution to Mayabunder, Diglipur, Hut Bay, Car Nicobar requires inter-island ferries. APWD tenders apply CPWD DSR base rates plus standardised addenda for: sea-freight transport overhead (typically 25-50% on imported materials), cyclone-zone overheads (M30 minimum concrete, CRS steel mandatory in coastal zones), and saline-environment material specifications. Major capital projects (port expansions, runway upgrades, new hospital construction) follow project-specific BoQs prepared on this CPWD DSR + addenda framework.
Frequently Asked Questions
Does APWD publish its own SOR?
No standalone publicly-hosted SOR. APWD circulars and tender NITs reference CPWD DSR with A&N-specific addenda. Engineers preparing APWD tenders pull rates from recent NIT annexures.
What sea-freight overhead applies?
Typically 25-50% above CPWD DSR base for imported materials (cement, steel, bitumen, finishes). Higher for outer islands (Nicobar group). Local materials (sand, aggregate from quarries on Andaman main island) use Andaman-zone rates.
Are there cyclone-zone provisions?
Yes — A&N is in IS 875 Part 3 highest wind-speed zone (50 m/s). Cyclone-zone provisions: minimum M30 concrete, CRS steel within 5 km of coast, structural redundancy in industrial buildings. These add 10-15% to structural cost above non-coastal CPWD baseline.
What about Nicobar islands specifically?
Nicobar (Car Nicobar, Nancowry, Great Nicobar) gets additional sea-freight overhead reflecting the further distance from Port Blair. Tribal-area protections also constrain construction methods.
Are NHIDCL projects in A&N?
NHIDCL handles strategic infrastructure including the proposed Great Nicobar Development Programme (port, airport, township). These use NHIDCL's MoRTH SDB framework, not APWD references.
